In the current study, a first attempt at using aluminum flakes for the manufacture of open-cell aluminum foams with the space holder method is presented. The method involves powder mixing, compaction, leaching, and sintering processes. Saccharose particles were used as space holders, and multiple parameters were investigated to optimize the manufacturing processing route in order to produce high-quality open-cell aluminum foams with a simple, economic, and environmentally friendly method. The implementation of aluminum flakes leads to foams with 80 vol.% porosity, an excellent internal open-cell porous structure, low green compaction pressures, and does not require the use of binding additives.
在当前的研究中，首次尝试采用空间保持法使用铝片制造开孔泡沫铝。该方法包括粉末混合、压实、浸出和烧结过程。蔗糖颗粒用作空间保持剂，并研究了多个参数以优化制造工艺路线，从而用一种简单、经济且环保的方法生产出高质量的开孔泡沫铝。使用铝片能够制造出孔隙率为80体积%的泡沫材料，具有优异的内部开孔多孔结构，所需的生坯压实压力较低，并且无需使用粘结添加剂。
